  • Welding Magnets

    I just bought 9 welding magnets off of ebay recently just got them today.
    I was wondering if they will mess up the welding arc or ground clamp or anything else.
    I will be useing them with MIG,TIG,STICK,AND PLASMA CUTTING.

    I have always found that welding tig on a part near a magnet was difficult but give it a go maybe its hust me

      I personaly dont like useing magnets and avoid them when ever possible.Although when I have used them I removed them as soon as possible and never realy had a problem with them.I recently had to use magnets on a fuel tank project to hold 20 guage sheet metal in place and tacked it in place with tig before removeing the magnets and tigging the project to compleation.I saw no problem with the magnets but I've heard from other people that they can pull the arc.
      To all who contribute to this board.
      My sincere thanks , Pete.

        Hey Richie,
        When my Tig instructor was here he had me clamp some test pieces to the bench with a spring clamp. When I reached for one of my magnets he told me not to use them when I tigging. He said it would effect the arc characteristics.

          dyn88 is right. I have experienced the same thing at times. Seemed like I can get away with it every once in a while but most times the arc starts acting funny. You can always give it a go on some mocked up scrap and see what happens.

            Magnets don't get along well with direct current. If you plan to use them, keep them well away from the arc area. Even doing that, you will occasionally get some influence, depending on how your weldment and the magnetic poles wind up alingning. I've seen the effect is MIG and stick welding. I don't TIG at this point, so it's an unknown to me.

              I have used them when I need to tack some pieces when I mig but thats only if I have no other option or I need a quick fix.

                Mag Interference

                I also have seen a notable change in the way a mig weld lays down near a magnet. I have always wonedered if those magnetic ground lead attachments caused the same effect.

                  Used them Both

                  Nothing like having that second set of hands,I been using them for years,a nd use them for tacking only, and the mag. ground is GREAT, even throug rust,Jack

                    I've definately experienced magnetic influence with the mig. Physics I guess.

                      magnet ground

                      i love the magnet ground, and use magnets a lot for MIG but take the magnets off after i tack it (saves the magnet )
                      thanks for the help
                      ......or..........
                      hope i helped

                        It's physics, and how electric motors, cyclotrons, etc. work: a current passing through a magnetic field produces a force at right angles to both.

                            Magnets can cause problems with your welding. But, not always.

                              I rarely use those magnets, but when I do, it's strictly for positioning and tacking.
